摘要:
A series of (hetero)arylpyrimidines agonists of the Wnt-beta-catenin cellular messaging system have been prepared. These compounds show activity in U2OS cells transfected with Wnt-3 alpha, TCF-luciferase, Dkk-1 and tk-Renilla. Selected compounds show minimal GSK-3 beta inhibition indicating that the Wnt-beta-catenin agonism activity most likely comes from interaction at Wnt-3 alpha/Dkk-1. Two examples 1 and 25 show in vivo osteogenic activity in a mouse calvaria model. One example 1 is shown to activate non-phosphorylated beta-catenin formation in bone. (C) 2009 Elsevier Ltd.
